Question

simplify.
3u - 8u

Explanation:

Step1: Combine like terms

We have \(3u - 8u\). Since both terms have the variable \(u\), we can factor out \(u\) and perform the arithmetic on the coefficients. So, \(3u - 8u=(3 - 8)u\).

Step2: Calculate the coefficient

Calculate \(3-8\), which equals \(-5\). So, \((3 - 8)u=-5u\).

Answer:

\(-5u\)
